Friday night I started changing out the MB,processor,memory on my rig. Worked on it for about 5 hours and then started again Saturday morning. Got it all completed and it was play time. The the new system was nice, boot time was fast and I wanted to do tweaking on this Asus Rampage Extreme. The temps and OCing to 3.5 was only around 84 degs on this water system. Was surfing the net and da wife wanted to do some shopping so we left. When I got back home and hit the start button that was all she wrote. Did all the quick checks...nuthin. Ya hit the button and a second later it cut out. First thing I did was take the MB out of the case, tried it no good. I started replacing one thing at a time,power supply,memory,processor..ect..ect. Well by the time I stopped nothing was connect to the MB.The only thing that was on the MB was memory,processor,power supply.....make a long story short it is a bad MB...LOL.Being since I know it takes a couple of weeks to get this resolved I went ahead and put my old system back together and also put the new processor on the old MB. I found out that I can only use 1 gig of memory with this processor. The new memory I brought won't work on this board. I wasted my whole weekend but look at the bright side of this...when I get the replacement MB I get to do this all over again....waaaaaaa!:help::help: The seller wanted to sent me a rebuilt MB. I said on a 5 day old board...I don't think so jack. He said that is the best he can do. I contacted Amazon and they said if they couldn't straighten this out by Tuesday they would credit my account 401.00...I said ok
